Answer:
By a factor of 3
Explanation:
In the photon energy formula , frequency and the energy content have a direct relationship. This means anything that is done to one of the parameters is the same that will be done to the other to have a balance.
In this equation: Energy=plank’s constant * frequency.
Energy is directly proportional to frequency.
Answer:
=24.25 ^−1
Explanation:
Let and be initial and final velocity of the body respectively,
be acceleration due to gravity ( 9.8^−2 ), ℎ be the height of the body.
=0 ^ −1
ℎ=30
we know that, ^2−^ 2=2ℎ
^2=2∗9.8∗30
^2=588
=24.25 ^−1
Answer: gamma rays < ultraviolet light < radio waves
Explanation: We have to explain the ordering we take into account a relationship for electromagnetic wave, which is given by:
c=λ*ν c is the speed of light. λ and ν are the wavelegth and the frequency of the waves.
Then we also know that the high frequency of these radiation correspond to the gamma ray (10^18 1/s) while the lowest correspond to radio wave (10^8 1/s) so:
The ultraviolet ligth is ranged at frequencies of 10^16 1/s located bewteen gamma and radio radiation.
as large frequency lower wavelength we can order these radiations from short to long wavelengths as follows:
gamma rays < ultraviolet light < radio waves
From largest to smallest- atom, nucleus, proton and electron
Answer:
for the people of the Earth traveling they last much more than 70 years
Explanation:
In order to answer this answer we must place ourselves in the context of special relativity, which are the expressions for time and displacement since the speed of light has a finite speed that is the same for all observers.
The life time of the person is 70 years in a fixed reference system in the person this time we will call their own time (t₀), when the person is placed in a ship that moves at high speed, very close to the speed of the light the time or that an observer measures on Earth, the expression for this time is
t = t₀ 1 / √(1 - (v / c)²)
We see that if the speed of the ship is very close to the speed of light the
the value of the root of the denominator is very high, for which for the person on Earth it measures a very large time even when the person on the ship travels has a time within its 70 years of life
In concussion, for the people of the Earth traveling they last much more than 70 years
